Treadmill emergency stop Q&A

Question (Rob W)
I am an electrical engineer and have a Trotter 525.
I want to install a magnetic or rip cord switch to the treadmill to ensure my son who has had an head injury doing physio is safe.
Do you sell the switch and cord? I can then drill, install and wire it up.
Answer (Parts for Treadmill)
Dear Rob,
Usually in new treadmills there is a magnetic safety key like this
On the back of the console there is a small piece of metal, usually glued (which keeps the safety key in place) and a sensor (also glued) which opens and closes a 2 pin circuit. There is no need to drill the console to install this.
The sensor has a wire of about 100 cm length, which goes down the treadmill posts to the motor compartment. Down there you usually find a controller board which gets the sensor signal, if it's open, it stops the motor power or doesn't allow it to start.
If there is no key on your treadmill (looks an old model), you could make a switch yourself so that the sensor controls the switch below and cuts the current in case the safety key is removed.
Is that what are you looking for? If the situation is not so bad, that could be good, but please note that there are on the market specific treadmills aimed at rehabilitation which have additional safety features (such as reduced speed, long handrails, automatic-speed setting, etc.), which can lower risks more than the use of the safety key which is designed for people in good physical standing.

Today we help Abraham, a man from Kenya who needs money to fund fracture repair surgery.

At Parts for Treadmill we believe that being physically active in life is the best medicine against diseases, especially to face the problem of ageing in our counties of the first world. This is the reason why we offer qualitative reasonably priced spare parts and service for the repair of fitness equipment.

In third world countries, unfortunately, people have different problems and sometimes we want to help. Thank to watsi we are helping today Abraham with a donation of 570 USD. We would like to share its story here. You can donate to any of watsi patient with an amount of your choice.
Abraham's story

Abraham is a casual laborer from Kenya. He is a hardworking father of one. Abraham is the firstborn in a family of four. He lost his parents when he was only ten, which forced him to drop out of school and to take care of his three younger sisters.
On his way to work, Abraham was aboard a tractor loaded with logs. Unfortunately, before reaching their destination, the tractor lost control and hit a wall. Abraham broke his leg, while the others only suffered minor injuries. Abraham is not able to walk on his own and experiences pain.
Fortunately, surgeons at Watsi's medical partner can help. Abraham will undergo a fracture repair procedure, called an open reduction and internal fixation. This treatment will enable him walk again and go back to work again Now, our medical partner, African Mission Healthcare Foundation, is requesting $968 to fund this procedure. Parts For Treadmill contributed with $570, needed to complete the crowdfunding.
“I pray to God to give me good health so that continue working hard,” says Abraham.

Abraham underwent fracture repair surgery.

Abraham’s surgery was successful. He experienced pain after the surgery but later became stable. When he recovers fully, he will return to his job of tree cutting.

“I wish to thank all who made my surgery successful. I am recovering on well,” he says.

E1 E2 treadmill errors/ speed sensor

The errors E1 and E2 on the treadmill often depend on problems with the speed sensor (when it is not a fault of other components). In fact, they indicate the wrong reading of the actual speed of the treadmill.
If you need spare parts or assistance, contact us

The most used sensor is the magnetic type (in the photo). In most cases, the sensor has a "cigar" shape while in some cases a square sensor is mounted. The square sensor is identical to the cigar sensor in the functionality. In both cases, before proceeding with the replacement it is advisable to check that the magnet placed on the pulley is close to the sensor (2-3 mm) otherwise the missing reading may depend on the fact that the sensor has moved due to the vibrations of the treadmill.
If the treadmill doesn’t start at all, please check the controller first.

Comparison of treadmill motors

The graph above shows the consumption in A of a 180V engine compared to a 110V motor. Consumption of 110V motor is much higher than a 180V power motor.

110V Icon Motor
Comparison RPM 110V-180V
The graph above shows the number of turns per minute (RPM) detected on 180V and 110V motors.
A 110V motor at about 20 volts has a spin speed equal to a 180V motor at a 50V working point.
Assuming a 150W load, the consumption of a 180V motor remains at about 3A, while that of a 110V motor is 7.5A, resulting in an increased risk of overheating the motor control board and motor.
For this reason, the use of 110V motors with high loads, in particular walking, should be avoided. Contact our engineers to replace 110V motors with 180V motors on your treadmill.

Treadmill assistance | error codes and troubleshooting

Error codes are based on Carnielli Treadmill. Some other brands/models share the same or similar error codes.
Generic errors
Possible cause: Treadmill does not work
1) Reason: no connection to power supply.
Solution: plug into socket. Check socket.
2) Safety key is not inserted
Solution: insert safety key in the monitor
3) Reason: Signal circuit system is cut off
Solution: Check control panel and signal / data cable
4) Possible cause: burnt fuse
Solution: Change fuse
Belt does not run properly
1) Possible cause: belt is not adjusted
Solution: adjust belt – follow instructions provided on our blog
2) Possible cause: Belt too tight
Solution: adjust the belt – follow instructions provided on our blog
Belt is slipping
1) Possible cause: Belt is too loose
Solution: adjust the belt
Errors E1, E2, E3
Errors E1, E2, E3 possible causes are the motor-to-board or motor-sensor-control board connections.
In most cases it is a damaged sensor, a burnt engine (excessive absorption) or a faulty motor control board.
a) possible cause: bad wire connection
solution: connect the wires again or replace wires / sensor
b) possible cause: faulty computer
solution: replace the computer
c) possible causes: faulty controller or motor
solution: replace the controller or the motor
a) possible cause: the motor wires does not connect well with the controller
solution: check the connection, disconnect and connect again. Steps as in E1 above.
Follow steps as in E1 above
Errors E5, E6
E5 identifies a current overload to the motor (so probably the motor is faulty)
E6 power problems at the console of the treadmill (therefore probable problems on the transformer of the engine board)
a) possible cause: damaged motor
solution: replace the motor
A) possible cause: damaged controller
Solution: replace the controller
Errors E7, E9
E7 identifies the lack of the security key
E9 problems with the inclination motor signal (probable failure on the inclination motor control)
a) possible cause: the computer does not receive the signal from the safety key
solution: check if the safety key is inserted / replace it
b) possible cause: the computer is damaged
solution: repair / replace main computer
a) possible cause: the controller could not check the signal from the incline motor (VR signal)
solution: check the VR wire and the connector, replace the incline motor
